# BulbyBox the onion-shaped money-box ## Abstract BulbyBox is an innovative piggy bank designed like an onion, perfect for pigs who love onions. To access the coins, you must break the onion, just like a real pig would do. ## Description To print BulbyBox, use spiralized outer contour (vase mode) to create a unique and functional design. This method allows for fast printing, making BulbyBox an excellent choice. Print it - Fill it - Break it - Enjoy Onion Ice Cream! [Watch this video](https://youtu.be/5b_AR7Sf0JA) to see BulbyBox in action. Note: For piggy thieves and onion enthusiasts, stealing money from BulbyBox is challenging but possible with enough time. However, when reversed, the coins lock together, making it difficult to steal. BulbyBox accommodates all euros and US dollars coins, making it a versatile option. Scale up the design for a larger model, but remember that the coin holes will also increase in size. ## Nerdy details you should know To enhance the robustness of the design, you can adjust the line width of the extruded plastic. However, this may affect the hole dimensions (wider lines result in smaller holes). I've done the math for you and included three designs with different line widths: 0.4mm (standard), 0.6mm (less ideal), and 0.8mm (more robust). Here's a summary table of adopted parameters and printer quality: | Nozzle diameter | Extrusion width | Effective Line Width | Layer height | Print Speed | Print Robustness | Print Quality | | --- | --- | --- | --- | --- | --- | --- | | 0.4mm | ~100% | 0.4mm | 0.2mm | Somewhat slow (2-3h with Ender3) | Easy to break when needed | Polished | | 0.4mm | ~150% | 0.6mm | 0.3mm | Faster | More robust | A bit layered but nice | | 0.6mm | ~100% | 0.6mm | 0.3mm | - | - | - | | 0.4mm | ~200% | 0.8mm | 0.4mm | Very fast (45min with Artillery Sidewinder) | Very robust (water tight) | A very nice layered effect | | 0.8mm | ~100% | 0.8mm | 0.4mm | - | - | - | Note: For saver-pigs and spendthrift-pigs, scaling up the design will increase the steal lock mechanism's efficiency but may reduce coin capacity. Scaling down may result in a smaller piggy bank for cents. Feel free to contact me for any requests or modifications.
